摘　　要：土地系统运行以土地可持续利用与人类福祉为准绳。以全国最大的生态移民区红寺堡区为例,基于不同计量方法和GIS空间分析法,对红寺堡区2000—2018年的“三生”用地转型及生态服务变化进行定量研究。结果表明:(1)红寺堡区基本形成以中部灌区生活生产、生产生态空间为主,周边为生态空间的“三生”格局,国土开发格局逐渐优化。(2)生产生态用地减少3.42×10^(4)hm^(2),生态用地增加1.24×10^(4)hm^(2),生态生产用地增加0.16×10^(4)hm^(2),生活生产用地增加2.02×10^(4)hm^(2)。(3)生态系统服务价值共增加11.18×108元。植被恢复是生态系统服务价值增加的主因,而建设用地对其他用地的侵占则是导致生态系统服务价值降低的主因。(4)协同推进山水林田湖草治理,做好已有生态用地的质量提升和绿地生态网络建设,通过优化生态系统服务结构提升区域生态系统的服务功能,从而实现生产空间的集约化发展、生态空间的提质增效及生活空间的优美宜居。The field of land use transformation aims to study the transformation process of land use forms corresponding to economic and social development.One of its manifestations is to study the transformation among the three leading functions of land,captured by the term ecological-production-living.The Eighteenth National Congress of the Communist Party of China put forward the national space development goal of“building intensive and efficient production space,livable and moderate living space,and ecological space with clear mountains and beautiful waters”,which has made land use transformation and its ecological effect from the perspective of ecological-production-living a hot topic in the field.Human activities have a significant impact on land use and the ecological environment in ecologically immigrated areas with large population changes.Hongsibu District in Ningxia,China is the main battlefield of a large-scale national water conservation project(the Ningxia Poverty Alleviation and Yellow River Irrigation Project),and it is also the largest single ecological migration area in China.Therefore,the impact of land use transition on the value of ecosystem services from the perspective of production-living land use can not only enrich the research content of this aspect at the county level but also provide a reference for decision-making regarding land use and ecological construction in arid ecological migrant areas.In this paper,image data from 2000,2009,and 2018 were processed using the ArcGIS 10.6 software and a land distribution map.Various measurement methods and GIS spatial analysis tools were adopted to conduct a quantitative study on the transformation of production-living land and the changes in ecological services in the Hongsibu District from 2000 to 2018.The results are as follows:(1)From 1990 to 2018,production of ecological land decreased by 3.42×10^(4)hm^(2) in Hongsibu District,whereas that of ecological land increased by 1.24×10^(4)hm^(2).The ecological production space also increased by 0.16×1
